Transcript of Macufacturing process of an egg carton

Egg Cartons Manufacturing Process of an Egg Carton Central Idea Materials can undergo permanent or temporary
changes which provide challenges and benefits
for society and the environment.

In my words this means: Anything of matter can experience long lasting or short lived changes which create difficulties and advantages for people and surroundings. Step 1: The raw material of an egg carton is
recycled paper! Step 2:Trucks go around and collect the scrap paper from people's blue recycling bins and take it to the factories. Bibliography http://www.tappi.org/paperu/all_about_paper/earth_answers/recycle2.htm The red bin is security locked to ensure your private documents are safe,these are not taken to the factories, whilst the blue bins are for your everyday recyclable paper. From the blue bins to the factory http://www.flagstaffgroup.com.au/recycling/iddex.html

(A pulper is like a giant mixer) This is what the inside of a pulper looks like. Step 4:Once the Pulp is ready, it has to be sieved (sorted through) to remove all the impurities e.g staples, ink, tape, labels etc. Step 5: After the pulp has been sieved for impurities it is transferred to a holding Mixer/Tank.The holding tank holds the pulp before it's taken to the forming machine. Step 6: After the pulp has been to the holding mixer, it is taken over to the forming machine. The pulp is poured in to the moulds for the carton to get its shape. This is how egg trays are formed. Step 7: Once the egg trays have formed they are taken to the dryer. Many cartons can be dried at once. Step 8: Once the cartons are dry and ready, they take the trays out of the dryer. Step 9: When the trays come out they are ready for packing. Step 10: Once all the cartons have come out of the oven they have a final packing to make sure everything is ready. Once everything is ready they take the egg cartons to the egg farms to be filled with eggs. After they had been willed with eggs they are taken to the grocery stores and the supermarkets. The change that the egg cartons experience is a chemical change because the new substance (egg carton) can't be changed back to the raw material (recycled paper), but what is interesting is that once an egg carton is put in a blue bin, the whole process starts again. After this whole process this is what the egg carton looks like. There are benefits and challenges with the manufacturing process of this material, with the environmental use of this material and of the people that use this material. Benefits
1. It is recycling.
2. People are employed to help run
the machinery.
3.They're a protective packaging.
4.They are easily stackable.
5. Companies can print there
logos on them.
6.Not many chemicals are used.
7. Even if the raw material gets wet it can still be used.
8.Their aren't many challenges. Although there are many benefits with this material there are also some challenges such as:
1. The electricity from the machines are polluted.
2.Ensuring that the machinery runs smoothly because if one part of the process stops everything has to wait. Not only do the manufacturers have responsibilities but people have responsibilities with this product too.
1. They have to make sure to put them in the right rubbish bin and ensure the material is recycled.
2. If somebody chooses not to throw them away they should make good use of them e.g. arts and crafts and seedling cups. Thank you for watching my inquiry. I hope you enjoyed! Created by Tahni!
